USA Baseball has advised us that the National Collegiate Athletic Association (NCAA) has provided official notice that the BBCOR decertification process has been implemented for the Marucci CAT5 33-inch model bat. Effectively immediately, this bat (Marucci CAT5 33- inch length) should be considered non-compliant and subject to Junior and Senior League Baseball Rules 1.10 and 6.06(d) and the USABat Standard. It should be noted that the National Federation of State High School Associations has taken similar action.
